hypercalciuria /hī′pərkal′sēyo͝or″ē·ə/ [Gk, hyper + L, calx, lime; Gk, ouron, urine] , the presence of abnormally great amounts of calcium in the urine, resulting from conditions such as sarcoid, hyperparathyroidism, or certain types of arthritis that are characterized by augmented bone resorption. Immobilized patients are often hypercalciuric. Some people absorb more calcium than is normal and therefore excrete greater than normal amounts into their urine. Concentrated amounts of calcium in the urinary tract may form kidney stones. Treatment is directed to correcting any underlying disease condition and limiting dietary intake of calcium. Also called hypercalcinuria. Compare hypercalcemia. −hypercalciuric, adj.
